Through work with the NZ Transport Agency, Federated Farmers, AgResearch and road contractors, DairyNZ is raising awareness to the problem.

The group’s message is that all land owners and the community as a whole is best helping out.Taranaki Regional Council’s environment services manager Steve Ellis said they have been cooperating to halt road spread.

He said: “Roading contractors have done a great job identifying the worst-affected areas so they can be mapped and shared with the public,”

“By teaming up with different organisations we’ve been able to get messages out through multiple networks.”
